How can i block a button with injection, during a time?
is there a command or, something, any way?

what do you mean?

For example in my shard before using bandages i have to wait 2 seconds after i can use them again. But if i press the bandaging button before 2 seconds i fail de bandaging action.
I have my bandaging macro in f1 hotkey, and i want to know if its possible to block the hotkey the 2 seconds that i need for not fail the bandage.

no, you can not block button, but you may modify script in way you need, using uo.Timer() function and global variables
